In 7beecaf7d507 ("net: phy: at803x: improve the WOL feature"), it seems
not correct to use a wol_en bit in a 1588 Control Register which is only
available on AR8031/AR8033(share the same phy_id) to determine if WoL is
enabled. Change it back to use AT803X_INTR_ENABLE_WOL for determining
the WoL status which is applicable on all chips supporting wol. Also
update the at803x_set_wol() function to only update the 1588 register on
chips having it. After this change, disabling wol at probe from
d7cd5e06c9dd ("net: phy: at803x: disable WOL at probe") is no longer
needed. So that part is removed.

Since the AR8032 part does not support wol, remove related callbacks
from it.

Does phy_read() never fail? Why remove the error checking?
